15 Δεκ 2012 · To decode a string, you would use the opposite shift (if you encrypt with shift = 2, decrypt with shift = -2). I'm also kind of new to C# and come from a C++ background, but I hope this approach works for you or makes it clear how to approach it.
The Confederate Cipher Disc was a mechanical wheel cipher consisting of two concentric discs, each with the 26 letters of the Latin alphabet, that was used for the encryption of secret messages of the Confederacy during the American Civil War (1861-1865).
EXAMPLE: The signal "2212, 3, 1122, 333," would indicate that "W" was the adjustment letter ("2212" being "W" in the non-ciphered code) and "1122" the key-number completing the cipher combination. The disk in this case would be arranged so that "W" would coinside with "1122". To send a Message in a Cipher.
15 Απρ 2021 · Confederate generals used Vigenère regularly during the civil war, and their messages were routinely cryptanalzed by Union officers. Figure 21.3: Confederate Cipher Disk for implementing the Vigenère cipher.
6 Νοε 2015 · I'm brand new to C# and I've started to make a cipher decryption program. The code works and runs fine, apart from the odd exception. I'm just looking for ways to improve my code and make more efficient. static void Main(string[] args)
12 Ιαν 2023 · The Cipher Feedback mode encrypts small increments of data smaller than the block size. The Cipher Text Stealing mode can produce an encrypted output the same size as the original unencrypted data set. CTS behaves exactly like CBC for all blocks except the last two blocks. In this example, we used CBC because it is a safer option to use when ...
24 Αυγ 2018 · This chapter looks at the cipher systems used by both the Union and Confederate sides during the American Civil War. It also presents a description of the biggest cryptanalytic breakthrough of the nineteenth century, the breaking of the unbreakable cipher, the Vigenère. Download chapter PDF.
